Everyone filed into the control room and gathered in front of the machine screen.
As written in science fiction, the cool and cool thing about technology is that rows of complex digital chart control images are floating around on the screen, just like mathematical and physical souls are flying.
"The operation interface seems very complicated." Dr. Ou Feng stood at the back, stood on tiptoes and took a look before saying.
If you haven’t learned it before, the first time you see it it will definitely be like reading a book from heaven.
The more intelligent the machine, the more accurate the calculated results must be, and the prerequisite must be more accurate in input data.
How to achieve the accuracy of input data? Refer to the previous membrane lung verification link. It is best to eliminate interference in the way of obtaining each number. It is best to have multiple verification methods to verify. To achieve this, for example, in the first step, the patient shaves
Do not shave your hair. In fact, you can not shave your hair with Gamma Knife, and it is best to cut your long hair short. The obvious advantage of shaving your hair versus cutting your hair short is that it can eliminate interference and help doctors and machines work more accurately.
Accurate positioning. Considering that this patient has seven tumors in his brain and is treated with the latest machines. Since hair loss may occur after radiotherapy, the patient’s appeal must be that it is best to eliminate all the tumors at once and simply shave.
Seeking the best for your hair
Precise positioning is better.
You don’t have to worry about shaving your hair, as your hair will grow back very quickly. What you are most afraid of clinically is that it won’t grow back, such as hair loss and baldness, which may not be cured. The second step is positioning scan, including repeated imaging examinations before treatment.
Doctors prefer to use magnetic resonance instead of CT because magnetic resonance does not produce metal artifacts compared to CT. The same reason is to obtain accurate data arrangement.
Eliminate interference. The third step of dosimetry can be called the patient's Gamma Knife treatment plan. We have just introduced the principle of Gamma Knife, such as where on the tumor the flying needle of the flying knife will be shot, and the intensity of the flying needle.
Density distribution maps, these require detailed planning by the doctor and are input into the machine in advance. The reference is the last positioning film after the patient is put on the head frame. Therefore, after the head frame is put on, the patient needs to enter the MRI room again.
Last scan positioning
.
A group of doctors stood here, fumbling with the machine's program, comparing it with the patient's previous magnetic resonance imaging, and carefully examining whether the treatment could be done properly, lest the patient be put on a headband and unable to repent.
Dr. Sun said honestly: "I can't guarantee 100% that I can treat her tumors in one go."
It means that some of the tumor lesions caught by Dr. Song's superhuman eyes are too small. In the eyes of the radiotherapy doctor, it is difficult to say whether these small ant-like dots are tumors. On the other hand, some small tumors are located close to the brain.
Important parts of the body, such as the thalamus we talked about before, are close to the brainstem. Although radiotherapy is not a real scalpel, there is a fear of accidental injury when killing tumors with a knife.
Surroundings or other parts, so for tumors located deep in the brain, such as neurosurgery, Gamma Knife doctors are particularly cautious about areas.
There are consequences for not killing the patient properly. Not only will it damage normal functional areas like neurosurgery, but it may even stimulate the surrounding free cancer cells to cause them to grow rapidly and put the cart before the horse.
Teacher Sun's concerns are reasonable. In view of the patient's current condition, it may be possible to consider not completing the procedure at one time, but wait until the tumor grows larger before undergoing a second procedure or directly adding whole-brain radiotherapy.
